School is like slavery in many aspects to be honest. Though it‘s really not a physical one, but a mental one.
You can not do much without getting permission from an authority figure first, including relieving basic biological needs such as eating or using the bathroom. You are not allowed to leave the facilities without permission. You are classified into different groups based on your performance on tests, and eventually seperated based on that (usually at high school/university level). You are trained for at least 12 years in this way to obey arbitrary rules and procedures, which are designed to get you ready for the capitalist hellscape that awaits you. Some countries even use this period of time to push another agenda on you, usually one related to religion &\ nationalism. At last, you come out of it (while probably having forgotten many of the things ”taught” to you) and you are immediately put into mandatory military service, or you come to the point of needing a service job just to survive.
Autodidacticism definitely rocks, and homeschooling would be a better idea if one was qualified for it and the child's social needs could be met elsewhere.
Kinda unrelated to your example, but I just wanted to expand on your psyop comment.
Hopefully...
